English Text:
The Prophet (Sallallahu Alaihi wasallam ) sent Mu`adh(Radiyallahu Anhu) to
Yemen and said, “Be afraid, from the
curse of the oppressed as there is no
screen between his invocation and
Allah.”

You Should Never by any means oppress any one, because you don’t know which kind of evil prayer he will do on you, and Allah will Certainly Answer His Invocation.
